- driveA30 host-side (tests/uat/lib/harness-page-driver.ts):
- import type { UserEvent } from '../../../src/shared/types' (5-type tuple grep).
- A30_EXPECTED_TYPES = ['click','input','navigation','js_error','network_error']
(canonical CON-event-log-schema 5-tuple).
- 3-phase pattern (page.evaluate stub → findLatestZip → JSZip
logs/events.json) per Plan 02-04 driveA26 analog.
- 6 host-side checks: A30.0a (entry present) + A30.2..A30.6 (5 type
presence). Filter-pipeline form; no `continue`.
- Orchestrator wiring (tests/uat/harness.test.ts):
- driveA30 import + driveA30Wrapped const + drivers-array entry with
Plan 03-02 banner; Architecture banner updated A29 -> A29, A30.
- assertA30 architectural rewrite (deviation Rule 3 — blocking fix):
The plan's original strategy "dispatch synthetic events ON the harness
page (chrome-extension://) so the production listeners on that page
fire" was empirically wrong on two counts:
1. Chrome MV3 `<all_urls>` match-pattern (Chrome match-pattern docs)
permits schemes http/https/file/ftp/urn only — NOT
chrome-extension. The harness page has NO content script attached;
the SW SAVE_ARCHIVE handler reported "Could not establish
connection. Receiving end does not exist." when the active tab was
the harness page (verified empirically 2026-05-20T17:36:25Z trace).
2. Even if (1) had been satisfied, page.evaluate-side fetch() runs in
the MAIN world while the content-script's window.fetch wrapper at
src/content/index.ts:167 patches only the content-script's
ISOLATED-world window. Page-world fetches NEVER reach the
production network_error wrapper.
Fix: A30 now creates a fresh https://example.com probe tab via
chrome.tabs.create (mirrors A27's pattern; DEC-011 Amendment 1 `tabs`
perm; `scripting` perm already in manifest); uses
chrome.scripting.executeScript with default `world: 'ISOLATED'` to
inject all 5 triggers directly in the content-script's realm; SAVEs
while the probe tab is active (SW harvests events.json from a tab
whose content script IS attached); cleans up the probe tab in finally
(T-02-04-04 silent-ignore parity). All 5 UserEvent types now land
empirically: type counts: click=1,input=1,navigation=1,js_error=1,
network_error=1; userEvents.length=5.
- UAT 30 → 31 GREEN; vitest 171/171 preserved; Tier-1 FORBIDDEN_HOOK_STRINGS
unchanged at 12 (A30 rides production chrome.tabs + chrome.scripting +
GET_RRWEB_EVENTS round-trip — no new test-only symbols).
Mokosh UAT harness (Plan 01-11)
Puppeteer-driven Node script that runs 14 assertions end-to-end against a real Chrome instance loaded with the Mokosh extension. Replaces Plan 01-09 Task 5's operator-empirical functional verification (the operator retains only step 1 — build — and step 14 — brand/design acceptance).
Quick start
npm run test:uat
This builds dist-test/ (the hook-enabled bundle) and runs the harness.
Exit 0 means all 14 assertions passed. Final line: UAT harness: 14/14 assertions passed.
Local-debug mode
HEADLESS=0 npm run test:uat
Opens a real Chrome window so you can watch the picker auto-accept, the badge transitions, the popup appear, etc.
Developer iteration tricks
# Skip the production build inside assertion 0 (uses existing dist/):
SKIP_PROD_REBUILD=1 npm run test:uat
# Run the harness against an existing dist-test/ (skip npm run build:test):
npx tsx tests/uat/harness.test.ts
Assertion catalog
| # | Title | Bug class | Hook used |
|---|---|---|---|
| 0 | Production bundle has no test-hook leaks | T-1-11-01 | filesystem grep |
| 1 | SW bootstrap → setIdleMode | — | sw.evaluate |
| 2 | Toolbar onClicked-idle → REC + popup | — | triggerExtensionAction |
| 3 | Offscreen displaySurface === monitor | D-15 | __mokoshTest.getCurrentStream |
| 4 | Toolbar onClicked-recording → popup, no new offscreen | — | targets count |
| 5 | SAVE_ARCHIVE → download fires | — | downloads polling |
| 6 | BUG B: simulateUserStop → badge OFF + no recovery notif | b9eeeeb |
dispatchEvent('ended') |
| 7 | RECORDING_ERROR codec-unsupported → ERR + recovery notif | — | sendMessage |
| 8 | BUG A: onStartup → mokosh-startup- notification creates | a881bf0 |

| 9 | Icon file sizes meet floors | Bug A precondition | sw.evaluate(fetch) |
| 10 | Manifest has notifications + 3 icons | Bug A precondition | chrome.runtime.getManifest |
| 11 | 35s recording → segments.length >= 3 | D-13 | __mokoshTest.getSegmentCount |
| 12 | ffprobe on extracted webm exits 0 | Plan 01-08 | jszip + execFile |
| 13 | Archive shape — video + meta.json version match | Plan 01-07 | jszip |
Failure isolation
Single browser, serial assertions, bail on first failure for setup- dependent assertions (assertion 0 abort means refusing to launch a potentially-leaky bundle). Per-assertion bail keeps the diagnostic output unambiguous — see RESEARCH §5 + Plan 01-11 open-question resolution 4.
On failure, the harness dumps the last 30 lines of SW console + last 30 lines of offscreen console (captured live during the run) to stderr BEFORE rethrowing — gives you contextual triage without needing to re- run with debug logging.
Known gotchas
Locale-specific picker auto-accept
The --auto-select-desktop-capture-source=Entire screen Chrome flag
auto-accepts the screen-share picker. The string "Entire screen" is
en_US-specific. If your Chrome is set to a non-English locale, the
picker option label will differ and the auto-accept will silently fail
(picker stays open; assertion 2 times out).
Fallback: switch your Chrome user-data-dir's locale to en_US for
harness runs, OR adjust the launch arg in tests/uat/lib/launch.ts to
match your locale's equivalent string.
dev-dep Chromium binary size
puppeteer pulls a ~150 MB Chromium binary at npm install time. CI
must accept this. Production npm install --omit=dev skips it cleanly.
Xvfb is NOT required
Per Plan 01-11 RESEARCH §3 empirical probes against Chrome 148, the
--headless=new mode handles screen capture without Xvfb on Linux CI
runners. If a future Chrome regresses this, Xvfb :99 & DISPLAY=:99 npm run test:uat is the fallback.
CI runner screen-capture concern
The 35s recording assertion (A11) captures whatever is on screen during that window. CI MUST run the harness in an isolated container with no concurrent workload — see T-1-11-02 in Plan 01-11's threat model.
Real Chrome download (assertion 5 → A12)
The harness configures per-page download behavior via CDP to a fresh
os.tmpdir()/mokosh-uat-downloads-* directory; downloads are NOT
written to your real ~/Downloads. The temp directory is deleted by OS
tmpdir GC.
